Settlement, habitat preference, reproduction, and genetic diversity in recovering the white-tailed eagle Haliaeetus albicilla population
The recovering population of white-tailed eagles Haliaeetus albicilla was studied in Lithuania, Central Europe. In the present study, we focused on (1) clarifying which theoretical distribution model better fits and describes the observed pattern of eagle settlement, (2) examining habitat preference...
